PPi and NTP binding. A comparison of the active site of the σS-TIC before NTP soaking with that of the T. thermophilus transcription elongation complex with the NTP analog AMPcPP (APC) (PDB ID code 2O5J) (gray) (A); the T. thermophilus TIC with ATP and CMPcPP (2TM) (PDB ID code 4Q4Z) (light blue) (B); the T. thermophilus transcription elongation complex with APC and streptolydigin (PDB ID code 2PPB) (wheat) (C); and yeast RNAP II elongation complex with 2′-deoxyguanosine-5′-triphosphate (dGTP) (PDB ID code 2E2I) (green) (D). The superimposition was performed using the β subunit of bacterial RNAP or the second-largest chain of the yeast RNA polymerase II.
